A faucet that won’t stop dripping, a kitchen remodel waiting on its new sink, or a bathroom vanity that needs its plumbing reconnected: Target Plumbers installs, replaces and repairs sinks and faucets in homes across Los Angeles and Orange County. We check the shut-off valves and drain under the sink before anything comes out, connect the new fixture with fresh supply lines, and run it until the cabinet stays dry.
| What you see | Likely cause | Usually |
|---|---|---|
| Drip from the spout with the handle off | Worn cartridge, washer or valve seat | Repair |
| Water pooling around the base of the faucet | Failed O-ring or base gasket | Repair |
| Weak flow from one faucet only | Clogged aerator or debris in the cartridge | Repair |
| Handle stiff, loose or hard to turn | Worn cartridge or handle adapter | Repair |
| Pull-down spray won’t retract or leaks at the hose | Worn hose, missing weight or failed quick-connect | Repair |
| Water in the cabinet under the sink | Supply line, valve or drain connection leaking | Repair the connection |
| Corroded or cracked faucet body, flaking finish | The faucet itself has failed | Replace |
| Same faucet repaired before, or parts discontinued | Repairs no longer cost-effective | Replace |
| Chipped, cracked or stained sink | Sink surface damage | Replace the sink |
Not sure which row you’re in? A photo of the faucet and the space under the sink helps us tell you before the visit. Water already on the floor? Close the two small valves under the sink, or the main shut-off, and call. For leaks inside a wall or ceiling, see water leak repair.
Send us the model number of the faucet you’re considering and we’ll tell you whether it fits your sink.
Faucets sold in California must meet the state’s water-efficiency standards (Title 20), which are tighter than many older fixtures:
| Faucet | Maximum flow |
|---|---|
| Bathroom (lavatory) faucet | 1.2 gallons per minute |
| Kitchen faucet | 1.8 gallons per minute, with a temporary boost to 2.2 allowed |
That’s why a new bathroom faucet can feel gentler than the one it replaced. If the flow is far below that, the cause is usually a clogged aerator or low household pressure, which a water pressure regulator check can rule out. Source: California Title 20 water-efficiency standards summary.
Drop-in, undermount and farmhouse sinks, single or double bowl. We connect the faucet, drain, trap, dishwasher drain and disposal, and set new supply lines
Vanity tops, pedestal, wall-hung and vessel sinks. When a vanity is replaced, we reconnect the drain at the right height and add new valves if the old ones are worn.
Pull-down, pull-out, bridge and single-handle faucets, plus side sprayers and soap dispensers.
Single-hole, centerset and widespread faucets, including the pop-up drain assembly that comes with them.
Quarter-turn shut-off valves, braided supply lines, P-traps and drain tailpieces, and a separate drinking-water faucet for an under-sink filter. Planning filtration for the whole house instead? See whole-house water filtration.
We tell you on the spot whether a part will fix it or the faucet has reached the end of its life, and give you both prices when both make sense.
California sets the line. Since 1 January 2025, someone without a contractor’s license may only take a job under $1,000, and only if the work needs no permit and they do it alone (CSLB, AB 2622). Swapping a faucet on working valves can fall inside that. Moving a sink, extending a drain or water line, or any job that needs a permit does not. Whoever you hire, ask for their license number and look it up on the CSLB website.
Doing the sink as part of a kitchen or bath update? The plumbing can go on a 0% plan for up to 48 months if you qualify.
The price depends on the type of faucet, whether the shut-off valves and supply lines under the sink need replacing, and whether the sink or countertop has the right number of holes. A straight swap on a sink with good valves is the simplest job; adding a sprayer, filter faucet or new valves adds parts and time. You get the full price before we start.
Only within limits. Since 1 January 2025, California lets an unlicensed person take a job under $1,000 only if it needs no permit and they work alone (CSLB, AB 2622). A simple faucet swap can fall under that; moving a drain, adding a water line or any job that needs a permit calls for a licensed contractor.
Yes. Bring the model number when you book so we can check the hole layout and connections ahead of the visit. Parts we supply carry our warranty; a fixture you supply carries the manufacturer’s warranty.
Faucets sold in California are built to lower flow limits than older fixtures: 1.2 gallons per minute for bathroom faucets and 1.8 for kitchen faucets. A sudden drop right after installation can also be grit caught in the aerator, which is why we flush the lines before fitting it.
If the faucet is in good shape and parts are available, a new cartridge, washer or O-ring usually stops the drip. Replace it when the body is corroded or cracked, the finish is failing, parts are discontinued, or you have repaired it more than once.
Often, on older homes. Valves that have not been turned in years can seize or start leaking the moment they are closed. We test them before removing the old faucet and quote new quarter-turn valves if they don’t shut off fully.
We handle the plumbing for undermount, drop-in and farmhouse sinks. An undermount sink is attached under a stone countertop, so the cut-out and mounting are usually done by the countertop fabricator; we connect the faucet, drain and disposal once the sink is set.
A single faucet replacement is usually finished in one visit. A new sink, a vanity swap or a job that needs new valves or drain parts takes longer. We give you a time estimate with the quote.
